    157157    You should see at least two interfaces:
    158     * The '''control interface'''. This is the interface from where you access
    159     the node, e.g. ssh into your host. The control interface is mainly used for
    160     control traffic, i.e. traffic for controlling the node and the experiment.
    161     The control interface usually has a publicly routable IP.
    162     * The '''data interface'''. This is the interface that is used for sending
    163     experimental traffic. This is the interface that connects to the other hosts
    164     of your experiment through GENI. The links between these interfaces are the
    165     ones that allow you to run non-IP experiments.
     158      * The '''control interface'''. This is the interface from where you access the node, e.g. ssh into your host. The control interface is mainly used for control traffic, i.e. traffic for controlling the node and the experiment. The control interface usually has a publicly routable IP.
     159      * The '''data interface'''. This is the interface that is used for sending experimental traffic. This is the interface that connects to the other hosts of your experiment through GENI. The links between these interfaces are the ones that allow you to run non-IP experiments.
    166160    i. Note the name and the MAC address of the control and of the data interface for each node. The data interface is the one that has an IP that starts with 10.
    167161    i. From the client ping the server. From the xterm that is logged in to the client type :
    … …  
    169163    ping server -c 5
    170164  }}}
    171     '''Note''': You can use the name that is assigned to the host to directly ping
    172   the host, you can also ping using the IP of the data interface of the node.
    173   An example output should look like :
    174   {{{
     165    '''Note''': You can use the name that is assigned to the host to directly ping the host, you can also ping using the IP of the data interface of the node.  An example output should look like :

    191183  sudo /sbin/ifconfig <data i/f name> 0.0.0.0
    192184  }}}
    193     '''Note''': Be extra careful to bring down the IP on the data interface,
    194   bringing down the IP on the control interface means that you will lose
    195   connectivity to your host.
     185    '''Note''': Be extra careful to bring down the IP on the data interface, bringing down the IP on the control interface means that you will lose connectivity to your host.
    196186    i. Try again to ping from the client to the server. In the xterm of the client type:
    197187    {{{
    … …  
    209199  sudo /usr/local/bin/pingPlus <server data mac addr> <client data i/f name> 12345
